<h3 id="rationale">Rationale:</h3>
<p><code>break</code> or <code>continue</code> was found outside a loop.
These statements are only valid in loops. In particular,
<code>break</code> is not required in <code>case</code> statements as
there is no implicit fall-through.</p>
<p>To return from a function or sourced script, use <code>return</code>.
To exit a script, use <code>exit</code>.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>It's possible to <code>break</code>/<code>continue</code> in a
function without a loop. The call will then affect the loop -- if any --
that the function is invoked from. This is obviously not good coding
practice.</p>
